Shell Programming and Scripting

Hi all,


In a directory of many files, I need to merge only files which do not have identical lines and also the resulatant merge file should not be more than 50000 lines. Basically I need to cover up all text files in that directory and turn them to Merge files.txt with 50000 lines each

Ex:

Code:

a.txt   b.txt c.txt  
A         C      F
B         D      G
C         E      H

In the above case a.txt and c.txt alone should merge , as a.txt and b.txt has value 'C' in common.
Can anyone help quickly?

I think, to get a response, you need to provide a better example of what you are trying to do, and use code tags.

Code:

grep -v -f file1 fil2
